Abstract

Prunus mume is said to aid in the recovery of fatigue and improvement of liver and stomach functions. To obtain the best benefits of the whole fruit, fresh green Prunus mume was de-seeded and the fruit pulp was vacuum dried. The vacuum-dried pulp was powdered and sieved through a 250 ${\mu}m$ sieve. Then the sieved green Prunus mume powder (GPP) was granulated with water (GPPGW) and with Prunus mume extract (GPPGE) with a fluid bed coater. The physicochemical and sensory properties of GPP, GPPGW, and GPPGE were then evaluated. As a result, the water dispersibility (dispersible time) of GPP, GPPGW, and GPPGE was 21.19 sec, 6.46 sec, and 4.85 sec, respectively. The powder fluency (angle of repose) of GPP, GPPGW, and GPPGE was $11.25^{\circ}$, $8.65^{\circ}$, and $9.52^{\circ}$, respectively. The overall consumer acceptance of GPP, GPPGW, and GPPGE was 3.50, 4.62 and 5.00, respectively. Inconclusion, Prunus mume can be used as granulated whole fruit pulp with good powder fluency and dispersibility.

청매는 피로 회복에 좋고 체질 개선 효과에도 좋으며 해독작용에도 도움이 되며 그 외에도 여러 가지 기능성을 갖는 건강기능식품으로 알려져 있는 청매를 씨만 제거한 후 건조시켜 분쇄하여 청매분말(GPP)을 얻었다. 청매분말을 유동층 조립기에서 유동하면서 물(GPPGW)과 매실 농축액 20%를 분사액으로 하여 과립(GPPGE)을 제조하였다. 과립의 물성측정 결과 청매과립은 청매분말보다 용해성과 흐름성이 우수하였고, GPPGE는 GPPGW에 비하여 흐름성은 좋지 못하였으나 용해성은 우수하였다. 일반성분 분석 결과 GPPGE에 조지방과 구연산 함량이 가장 높았으며, GPP와 GPPGW 사이에는 성분에 큰 차이가 없었다. 관능특성 분석결과 GPPGE가 가장 반짝이는 녹색을 나타내었고 과립이 쉽게 깨지는 특성을 나타내었다. 관능특성과 소비자조사결과에 대한 상관분석결과 소비자들은 반짝이는 외관을 갖고 과립이 쉽게 깨지는 특성을 가진 GPPGE를 가장 선호하는 것을 알 수 있었다. 따라서 유동층 조립기에 청매분말을 유동시키면서 청매추출액을 분사하여 제조된 과립(GPPGE)은 청매 과육전체를 섭취하면서 편리성이 증진된 새로운 형태의 제품으로 이용이 가능할 것으로 판단된다.
